The song does not contain any nugget of purest... green. It is in episode 4 ("Money").Before clue #3 I wanted to go with something else, but now for whatever reason I've got The Alchemist stuck in my head. So I'm going with that.
I laugh in the face of probability!Oh, that's a great guess! Probably correct.
I laugh in the face of probability!
Nah, just kidding
It's Chains Of Misery:
Clue #1 is a line from Ugly Kid Joe's Madman. COM has the lyric: "There's a madman in the corner of your eye".
Clue #5: Savatage released Gutter Ballet in that year, COM has this to say: "There's a prophet in the gutter in the street". Also, both Gutter Ballet and A Night At The Opera feature songs with a love theme (She's In Love, Love Of My Life). COM kinda fits in there.
Got an inkling about the other clues, but nothing really concrete.
